Introduction
Whether you’re hawking holiday ornaments or summer swimwear, seasonal selling on eBay can be hugely profitable – but only if you master your tax obligations. This guide walks you through the key federal and state rules that apply when your online store heats up (or cools down), so you can focus on making sales instead of scrambling at tax time.
Tax Code References
- Gross Income (IRC § 61): All amounts received from your eBay business must be included in gross income.
- Self-Employment Tax (IRC § 1401): Net earnings from self-employment are subject to Social Security and Medicare taxes.
- Information Reporting (IRC § 6051): Marketplaces must issue Form 1099-K for qualifying transactions.
Relevant Forms
- Form 1040, Schedule C: Profit or Loss from Business
- Form 1040-ES: Estimated Tax for Individuals
- Schedule SE (Form 1040): Self-Employment Tax Calculation

Detailed Example
Scenario: Priya sells handmade winter scarves each November–January. In 2025:
- Gross Sales: $40,000
- Expenses: $15,000 (materials, shipping, eBay fees)
- Net Profit: $25,000
Tax Impact:
- Income Reporting: Priya reports $25,000 on Schedule C (IRC § 61).
- Self-Employment Tax: Computed on Schedule SE at ~15.3% of net profit (IRC § 1401).
- 1099-K Reconciliation: eBay issues Form 1099-K because Priya exceeded $20,000 and 200 transactions; she reconciles it against her records to avoid discrepancy.
